I needed a small headless UPnP media renderer for Linux (for small footprint-use in a Raspberry Pi or CuBox), but there does not seem to be much small stuff around.

Found: GMediaRender http://gmrender.nongnu.org/ but it was incomplete, several basic features missing and the project seems to have been abandoned some time ago.

So this is a fork of those sources to resurrect this renderer and add the missing features. (Original sources at http://cvs.savannah.gnu.org/viewvc/gmrender/?root=gmrender )

I consider this fork GMediaRender 0.0.7 (license to trill).

Added so far

• Support to get duration and position of current stream. This allows controllers to show a progress bar.
• Support basic commands (Only Play and Stop were working before)
  • Pause : Pause current stream.
  • Seek : Seek to a particular position.
• When current track is finished, transition to state STOPPED so that the controller sends us the next song (Actively eventing).
• Support gapless (via SetNextAVTransportURI to play gapless). Looks like the next version of BubbleUPnP will send the right action to support it.
• Volume/Mute control.

TBD

• go into TRANSITIONING while seeking.

Tested the following control points: BubbleUPnP, 2Player, DK Player, eezUPnP; Please report what other control-points worked for you - and which didn't.

There are reports, that the sound output is flaky in recent versions of Raspbian Wheezy on Raspberry Pi, probably due to pulseaudio, missing gbus or gbus-session or something -- I don't know since I don't have a Raspberry Pi (yet). So if someone gets it to work properly, please send me an init-script for other people to try. And of course, debian packages for Raspberry Pi would be probably the best.
